Ohpir FL400A-LP2-50 400 W Fan-Cooled thermopile sensorwith 50 mm Aperture|China supplier

The FL400A-LP2-50 thermopile sensor is a fan cooled laser power and energy thermal sensor for high power density and long pulse lasers. It has a 50 mm aperture and can measure optical power from 100 mW to 400 W continuously and to 500 W intermittently. It can measure energy from 250 mJ to 600 J. Its high damage threshold LP2 coating covers the spectral range 350 to 2200 nm and 10.6 µm.

• LP2 type 350 to 2200 nm absorber for long pulse lasers
• Fan-cooled 0.1-400 W continuous power measurement
• 250 mJ to 600 J pulse energy measurement
• 500 W power measurement intermittently
